\(300\) pairs of shorts in total.
\(160\) are casual wear and \(200\) are swimwear.
\(80\) percent of the casual wear can be used as swimwear. So \(128\) casual wear can be used as swimwear.
Only casual wear \(= 160 - 128 = 32\)
Only swim wear \(= 200 - 128 = 72\)
Both \(= 128\)
Total \(= 32 + 72 + 128 = 232\)
Shorts are neither casual wear nor swimwear \(= 300 - 232 = 68\)
Answer \(B\)
